The cost of a field trip is \$220 plus \$7 per student. If the school can spend at most \$500, how many students can go on the field trip?

Set up the inequality where s is the number of students:
C(s) = 220 + 7s

We want C(s) <= 500, since at most means no more than
220 + 7s <= 500

Using our inequality calculator, we get:
s <= 40
